DLMS meter Reading POC (UGVCL, Gujrat)

Project Overview

Uniconverge Technologies partnered with Uttar Gujarat Vij Company Ltd. (UGVCL) to develop a proof of concept (POC) for advanced meter reading in areas with unreliable or unavailable cellular networks. The project focused on implementing a LoRaWAN-based solution to facilitate remote meter reading across challenging environments in Gujarat.

Challenges and Objectives

• Remote Locations Without Cellular Coverage: Many areas under UGVCL's jurisdiction lack reliable cellular network coverage, making it difficult to implement traditional remote meter reading technologies.
• Accurate and Timely Data Collection: Ensuring accurate and timely collection of meter data was critical for efficient billing and energy resource management.
• Seamless Integration with Existing Systems: The solution needed to integrate seamlessly with UGVCL's existing infrastructure, particularly the L&T utility meters, using the DLMS (Device Language Message Specification) protocol.

Our Solution

Implementation of DLMS Stack on LoRaWAN Network

Uniconverge Technologies deployed the DLMS stack over a LoRaWAN network to enable secure and reliable data communication over long distances. This solution allowed UGVCL to perform remote meter reading without relying on cellular networks, ensuring consistent data collection across all locations.

Remote Meter Reading in Non-Cellular Areas

Utilizing the LoRaWAN network's ability to provide connectivity over long distances and in areas with challenging terrain, the solution enabled UGVCL to gather meter readings from remote areas with no cellular coverage, ensuring uninterrupted service.

RS485 Interface for L&T Utility Meters

The L&T utility meters were connected to the LoRaWAN system via the RS485 interface, enabling smooth data transmission using the DLMS protocol. The RS485 interface was chosen for its reliability and ability to transmit data over long distances with minimal interference.
